NVIDIA released the GeForce 310.70 WHQL software suite, which isn't much more than a WHQL-signed version of the GeForce 310.70 beta drivers posted a couple of weeks ago. Available for 64-bit and 32-bit versions of Windows 8, Windows 7, Windows Vista, and Windows XP, the drivers, much like the 310.70 beta, are a cumulative of several R310 beta releases from over the past two months. They add significant performance increases over the previous 306.97 WHQL drivers.

I think the developers must say if it is or not beta. It has always been like that. MS certification is added value but not the end of all ends. I think this is not my opinion, but how things have been and are. Personal Computers (PC) are one thing and MS is another, although now we are "drilled" to say things like "Games for windows" instead of "PC game", etc... Applelization at it's best... : )
